Última Fisheries for orange roughy (Hoplostethus atlanticus) on seamounts in New Zealand ArchiMer Clark, M. Major commercial fisheries for orange roughy (Hoplostethus atlanticus) occur on seamount features, which are widely distributed throughout the New Zealand region. When the fishery developed in the late 1970s to early 1980s, it occurred mainly on flat bottom, but over time has become more focused on seamounts. In the 1995-1996 fishing year, it is estimated that about 70 % of the catch of orange roughy within the New Zealand EEZ was taken from seamounts. Seamounts on the Chatham Rise have been fished for over ten years. Examination of commercial catch and effort data show strong declines in catch rates over time, and a pattern of serial depletion of seamount populations, with the fishery moving progressively eastwards to unfished seamounts along the southern...

Age is a necessary parameter used in population dynamics to assess the state of exploited resources. This parameter is poorly known for most deep-sea species (depth > 400 m). This work focused on age estimation from otoliths of Alepocephalus bairdii (Alepocephalidae), Coryphaenoides rupestris (Macrouridae), Helicolenus dactylopterus (Sebastidae) and Hoplostethus atlanticus (Trachichthyidae), which French fishery exploitation, off the west coasts of the British Isles, began the late 1980's. Considering otolith growth zones as annual, the four species all show high longevity: 38, 54, 43 and 130 years, respectively, together with slow growth. The differences in growth between sex were estimated and difficulties in accurately estimating the age were...

Ano: 2000 URL: http://archimer.ifremer.fr/doc/00000/10396/7690.pdf Catch Per Unit Effort of deep-sea species off the continental slope to the west of British Isles. ArchiMer Girard, Marine; Lorance, Pascal; Biseau, Alain. Catch Per Unit Effort (CPUE) trends of the main target species of the deep-sea fishery were recorded for one sample trawler in two areas to the west of the British Isles, from 1993 to 1997. Considered species were the orange roughy (Hoplostethus atlanticus), the roundnose grenadier (Coryphaenoides rupestris), the black scabbard fish (Aphanopus carbo) and two squalid sharks: the Portuguese dogfish (Centroscymnus coelolepis) and the leafscale gulper shark (Centrophorus squamosus). Two sources of data have been used: the catch and effort database of IFREMER and the personal logbooks of the skipper from the sample trawler. The personal logbooks indicate the catch per haul, whereas the IFREMER database provides the catch and effort per day and statistical...
